I'd say 9 out of 10 of my potential posts, I get about 3/4's of the way through typing them and then think better of it.
Don't know if that's lazy or just good self censorship.
The other morning I was busting and my flatmate was in the shower, instead of waiting I pissed in a bowl and chucked it a few stories out the window when the coast was clear.
Think this one of those posts I should have scrapped!
